f'o all iokoiii it may concern I Be it known that 1, WILLIAM P. DAVIES,

oiBellevue, State of Kentucky, have invented certain new and useful -Im rovements in Mountings for. Railroad-Rails; and I do hereby declare the followin to be a full, clear,=-and'exact descri tion a? the invention,

l such'as will enable-t ers skilled in the art to :which it appertains to make and use the same."

This invention relates to improvements in "mountings for railroad rails, such for exampie as stringers, ties and chairs -the object of the invention bein to rovide a cushloning structure which s all e particular] apphcable for use with or forming part 0 concrete ties or other foundation members and which shall operate to protect such concrete base members, as well alsov as the rolling equipment, from sudden hammerlng, shocks and strains which mighttend to deteriorate the concrete foundation member or subject theirolling equipment to wear and rough usee; a "filth theseand other objects in v1ew,'the

invention consists in certain novel'features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings Figures 1, Quad 3 are'views illustrating the application of my improvements to a railroad'tie. Fig. 4 is a plan view showing the cushioning devices arranged lon 'tudinall under the rails and transverse y overt e ties, and

dcvicescomprise a base member 2 having dcprcssed'fianges 8 at -its edges, and an upper or cap member 4 also having de ressed flanges 5, at ;its edges, the cap mem er being made to telescope over the base member, eloselyfittin the outer walls of the latter sofas to c ect .air. tight connection, and

ing through the flange 3 and through the concrete moi-said bots also passing freely through hoes in the flange 5 of the cap member 4 and provided with keys 7 to limit the ulpward movement of said cap member. T e bolts 6 may also be provided with keys 8 under the tie. The cap memher 4 serves to receive the rail 9 and suitable fastening mcans areprovided on said cap member for securing the rail thereto. A duct 11 is made in the tie and is 0 on to the air at one end, the inner end of sai duct being made to communicate with the air space v12 formed by and between the telescoping members 2 and 4. A strip of wood or other yielding material 13 is laced loosely within the air chamber 12 an constitutes a valve for the port 14 of the duct .11. The upper cap member 4 of the cushioning devices is maintained normally in and returned to its normal position, by means of a weighted lever 15,-said lever being pivotally supported at 16 and its short arm being made to engage under the rail, or a spring such as shown in Fig. 7 may be employed, and weighted levers or springs may be located at both ends of the cushioning devices.

n the construction shown in Fig. 4, the cushioning devices are arranged transversely over, the ties as indicated at 17 and 10 imdinally under the rail,--two or more 3% the cushioning devices being arranged in line with each other under each rail section and spaced apart between adjacent ties. The

cushioning devices thus arranged produce, in efi'ect, stringers for the rail and the weighted levers, such as indicated at 18, Fi 4, may be located between the adjacent ends of each two cushioning devices 17 In Figs. 5, 6, 7 and 8, my improvements are shown apghed to a railroad chair,-the concrete foun ation member of which is indicated at 19. In other res ects, the construction of the devices is t e same as in Figs. 1, 2 and 3, except that elliptical springs 20 are shown at each end of the cushioning devices 21, instead of weighted levers. It is evident however, that either s rings or weighted levers may be employe for raising the cap member of the cushioninr device, with any of the arrangements shown in the drawings;

ing devices which will absorb shocks. and protect the concrete foundation members from the, eifects of hammering strains. If desired the ducts leading to air chambers of a pluralityof cushionmg devices may be connected. 7 a r Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope andhence I do not wish to restrict myself to'the precise details herei in set forth.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent is 1 lJThe combination with a foundation member, of cushioning means for a rail thereon, said cushioning means comprising relatively-movable members forming an air chamber between them, means securing the lower member of the cushioning means to the foundation member, and means for supplying said air chamber with air.

2. The combination with a concrete foundation member, of cushioning means there on, said cushioning means comprising telescoping members forming an air chamber between them, an air duct 1n the foundation member and communicating with saidv air chamber, the upper member of said cushioning means adaptedito support a rail, and yielding means for raising said upper member of said cushioning means. 7

3. The combination with a foundation member, of cushioning means mounted thereon, said cushioning means comprising relatively movable members-forming an air chamber between them, a duct 1n the founrdation member and communicating with 40 said air chamber, yielding means for raismg the movable member of said cushioning means, and a strip mounted in the bottom of said air chamber and constituting a valve for said duct.

4. Cushioning means for '"railroad rails,

comprising.irelatively movable members forming an air chamber"""between them,

meansforfsecuring the l'ower member toaa foundation, means for supplyingiair to said air chamber, and yielding means for raising the upper member. r I 5. Cushioning means for railroad rails, comprising relatively movable telescoping members forming an air chamber between them, means forrigidly securing the lower member tora foundation, the upper memmember having an air inlet, a valve nor- 'mally closing said inlet, and yielding means r i 1 6, The combination witha concrete base 'member, of cushion ng means comprising forfraising the upper member,

relatively movable members forming an air ber adapted to. rjeceive a rail, the lower chamber between them, the lower member of said cushioning means formed to receive a portion of the concrete base member, means" securing said lower member to the foundation member, an, air duct communicating with the air chamber, a valve in said'air chamber for said duct, and yielding means for raising the upper member of said 'cushioning means.
